About us

History

Oranje-Nassau Groep B.V. (ONG) has roots in the Maatschappij tot Exploitatie van Limburgsche Steenkolenmijnen, which secured the ‘Oranje-Nassau’ coal mining concession in the Dutch province of Limburg in 1893. Oranje-Nassau Mijnen at that time was the largest private mining company in the Netherlands. The last of its four mining operations was closed down in 1974.

During the last decade of the declining coal mining industry, ONG gradually transformed its mining business into an investment company, focusing on companies, property and energy.

The energy division, Oranje-Nassau Energie B.V. (ONE), entered the oil and gas industry in 1967 at the invitation of a group of American and British oil companies. It was invited to participate in the first round of acreage licensing on the Dutch Continental Shelf. Since its entry into the oil and gas market, ONE gradually developed into an internationally-oriented active investor in the upstream sector.

Following a strategic review of its activities, Oranje-Nassau Groep, the former parent company of ONE, decided to divest its energy business at the end of 2008. In May 2009, the divestment of ONE to a consortium consisting of ONH B.V. (a private Dutch investment company controlled by Marcel van Poecke), Dyas UK Limited and Sumitomo Corporation was completed. ONH B.V. retained ONE along with its management team, and acquired the Dutch and Gabon assets plus a minority stake in the offshore UK Buzzard oil field.

Strategy

Oranje-Nassau Energie B.V. (ONE) has a strong focus on the North Sea as its core area of operations. ONE has the ambition to significantly expand its operated and non-operated business in this region over the next 3 to 5 years, and is looking to further build on its existing presence in Gabon. Through our excellent subsurface, operational and commercial capabilities, ONE is uniquely positioned to capture growth opportunities and create both short and long-term value for all its stakeholders. Successful acquisitions of Sterling and Sean are excellent examples of ONE’s ability to execute this strategy with significant success. ONE is also actively looking at development and exploration opportunities to support our long-term growth aspiration, preferably ONE-operated assets, both within and outside of our existing portfolio. The Ruby discovery in the Dutch North Sea bordering Germany is evidence that there are still underexplored areas in the North Sea.
